PAINT.

1,205,267. p fi a m of Letters Patent Patented Nov. 211, 11916. No Drawing. Applicatiqn filed November-19, 1912. Serial No. 732,195/

' Be it known thatwe, Aueusrr. J. Ross: and CHRISTIAN M. EDWARD SCHROEDER, both citizens of the United States, and residents,

respectively, of Niagara Falls, in the county a of Niagara and State of New York,-and of o Rutherford, in the county of Bergen and State, of New Jersey,[have jointly invented Our invention relates to paints, thereby meaningthe well known substances applied .to surfacesfor coloration or protection, etc., at present usually composed of a pigment such as whitellead or zinc oxid ground toas the Well known gether with such vehicle drying oils, as for instance linseed oil, and

applied in the usual manner by brushing or the like to the surface treated.

The objects of our invention comprise the improvement of such paints in their covering, or hiding, qualities, their durability, resistanceto the weather, and to destructive or discoloring agents, present, for instance, as in'foulf air, or in vapors charged with hydrogen sulfid, etc.,

less cost than the best paints heretofore manufactured.

We have discovered that titanic oxid, as

such, now procurable in quantity as an amorphous powdered high percentage, say from 96% to 99% of chemically; uncombined TiOQ said powderwhen of highest purity, or

being white slightly yellowish or. bufi' in shade in proportion to. the presence, if any, of minute quantities of iron oxid uncombined with said TiO is,*owing such 'I iO capable of attaining our said objects when, in production of paint, substituted, in whole or in part, for the heretofore as, for example, white employed pigments, lead or zinc oxid.

To preduce'our'nov el paint we proceed as heretofore practised in the preparation of any desired paint, excepting, that, in lieu of the pigment formerly therein employed, we substitute, altogether, or to such extent 'finely powdered state,

and, also to produce paints havlng these lmproved qualities, at

product containing a to the peculiar properties of quantity of titanic oxid in being, for example, amorphous powder as desired, a

that contained in the above referred .to.- i,

Further description is, webelieye, unnecessary to enable those skilled in the art to produce our said paints,-since'it'follows that our titanic-oxid pigment is'mixed, or also ground, with a drying oil, such as linseed oil, or other suitable vehicle, such as dissolved gum or other tially the same. proportions and manner as white lead or zinc oxid, and is then ready for application, in any convenient manner,

to the surfaces to be covered, as by brushing on, or otherwise. 7 a

It will be understood that the whiteness of our resulting paint, other things being equal, is proportional to the amount of pure or uncombined TiO supplied thereto by the aforesaid amorphous powder employed as pigment; also that its improved qualities are proportional to the extent to which such titanic oxid is substituted for said hitherto employed pigments, the ideal embodiment of ourinvention being a paint the entire pigment of which is such titanic oxid. Among the numerous advantages; and superior qualities attributable to our said novel ,paint we note that it is uninjurious also that it has we believe, attributable to the comparative stability of titanic oxid; also thatit is more economical of-production at the of titanic oxid compared with. white lead or oxid of zinc.

We are aware that, prior to our invention, the incorporation into pigments of titanic oxid in crystalline form -or in chemical combination with other substances, has been suggested, the which we do not claim as our invention which consists broadly in our discoverythat only in its amorphous form'and or hiding, power as comvarnish, in substanl-to animal life inproportionto its content of harmless titanic oxid as compared to poisonorate previously employed paints, this being, i r

present cost chemically uncombined with other substances can titanic oxid in paints produce the best, if indeed any satisfactory, results.

What we claim as new and desire to secure by Letters Patent is the following, viz

1. Paint comprising a pigment containing amorphous, white, titanic oxid (Ti(). un-' combined chemically with other substances.

2. White paint containing a pigment-composed principally of amorphous, white, titanic oxid (TiO uncombined chemically with other substances.

3. Paint containing a plurality of pigments, one of which contains amorphous titanic oxid (TiO uncombined chemically with other substances.

4:. White paint containing a plurality of pigments, one of which contains amorphous, White, titanic oXid (TiOQ uncombined chemically with other substances.

5. Paint comprising a slightly yellowish or buff pigment which contains iron oxid and not less than 96% of amorphous titanic oxid (TiO uncombined chemically with other substances.

6. Paint containing amorphous titanic oxid (Ti() uncombined chemically With more amorphous titanic oxid (TiO uncombined chemically with other substances. 9. Paint containing iron oxid and also amorphous titanic oxid (Tio uncombined chemically with other substances.
